LP8345

Low Dropout, Low IQ, 500mA CMOS Linear Regulator

General Description

Features

1.5% Typical V_OUTtolerance

The LP8345 low-dropout CMOS linear regulator are avail-

able in 5V, 3.3V, 2.5V, 1.8V or adjustable output versions.

Packaged in our 6ld LLP package and 3ld DPAK they can

deliver up to 500mA output current.

n 210mV Typical Dropout 500mA (V_O= 5V)

n Wide Operating Range

2.7V to 10V

n Internal 500mA PMOS Output Transistor

n 19µA Typical Quiescent Current

n Thermal Overload Limiting

n Foldback Current Limiting

n Zener Trimmed Bandgap Reference

n Space saving LLP package

n Temperature Range

Typical dropout voltage

500mA is 210mV for the 5.0V

version, 270mV for the 3.3V version and 335mV for the 2.5V

version.

The devices include a zener trimmed bandgap voltage ref-

erence, foldback current limiting and thermal overload limit-

ing.

The LP8345 features a PMOS output transistor which unlike

PNP type low dropout regulators requires no base drive

current. This allows the device ground current to remain less

than 50µA over operating temperature, supply voltage and

irrespective of the load current.
